With the « direct to disk » engine, Streamosaur could record unlimited
broadcast (depending of your hard drive free space), in wav file format
or mp3. To use mp3 encoder it’s necessary to setup the lame mp3 encoder:
for that follow the instructions described in http://www.wavosaur.com/streamosaur/setup-mp3-encoder.php.

Streamosaur is a completely portable software without entries in registry.
Streamosaur doesn’t need installer: unzip the file in a directory and launch the exe file.
